Custom Action Filter Attribute

public class CheckSessionAttribute : System.Web.Http.Filters.ActionFilterAttribute 
{

    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        HttpContext ctx = HttpContext.Current;
        var userName=HttpContext.Current.Session["UserName"].ToString();            
         string lgnUser = HttpContext.Current.User.Identity.Name;         
         if (string.IsNullOrWhiteSpace(userName) || (userName != "superadmin"))
        {
          var response = actionContext.Request.CreateResponse(HttpStatusCode.Redirect,"Your session has expired. Please Click 'OK' to redirect to login page.");
         actionContext.Response = response;
         }
         else
         {                
             base.OnActionExecuting(actionContext);
         }
    }
}

Implementation

[CheckSession]
[RoutePrefix("api/products")]
public class ProductsController : ApiController
    {
        private Product product = new Product();

        [CheckSession]
        [HttpGet, AllowAnonymous, Route("getAllproducts")]
        public HttpResponseMessage GetProducts(int pageNumber = 1, string orderBy = "CreatedOn", string sortingMethod = "DESC", string searchWord = null)
        {
            int organizationID = 0;
            ProductsResponse productsData = new ProductsResponse();
            try
            {
                productsData = product.GetProducts(organizationID, pageNumber, 20 , orderBy, sortingMethod, searchWord);

                if (productsData.Errors.Count == 0)
                {
                    return Request.CreateResponse(HttpStatusCode.OK, productsData);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
            return Request.CreateResponse(HttpStatusCode.BadRequest, productsData);
        }
}
